ATTACHMENT FOR STEAM-BOILERS.

Application filed anuary 26, 1915. Serial No. 4,526.

To all whom it may concern:

Be it known that I, lVILLLiAM MULLER, a citizen of the United States of America, residing at Ambridge, in the county of Beaver and State of Pennsylvania, have invented certain new and useful Improvements in Attachments for Steam-Boilers, of which the following is a specification, reference being bad therein to the accompanying drawing. 7

This invention relates to an attachment for steam boilers and has for its object to provide means, in a manner as hereinafter set forth, to overcome the collecting of sediment at the entrance end of a boiler so as not to retard the passage of the heat units, under such conditions facilitating the generation of steam. The device is designed primarily to overcome the congregating of sediment at the bottom of the entrance end of a boiler whereby the retarding of the heat units at such end will be overcome and the heat units will pass more quickly through the boiler, under such conditions facilitating the generating of steam.

With the foregoing and other objects in view the invention consists of the novel construction, combination and arrangement of parts as hereinafter more specifically described and illustrated in the accompanying drawings wherein is shown an embodiment of the invention, but it is to be understood that changes, variations and modifications can be resorted to which come within the scope of the claims hereunto appended.

The drawing illustrates, in a side elevation, a steam boiler, broken away, showing the adaptation therewith in sectional elevation, of an attachment in accordance with this invention.

Referring to the drawings in detail 1 denotes a boiler shell, 2 the fines and 3 the fire box. The foregoing may be of any suitable construction.

The attachment consists of an elongated tube 5 which projects down between the fiues 2 and to a point in proximity to the bottom of the shell and extending down through said tube 5 is a shaft 6. The tube 5 projects up through the shell 1, and base 9. Secured to the base 9 is a support 10, provided with a yoke-shaped member 11, into which Copies of this patent may be obtained for Specification of Letters Patent.

projects the upper end of a shaft 6. The member 11 has a transverse arm 13, which carries a bearing 14:, and said shaft 6 extends up through said bearing 14 and carries a beveled gear 15. Journaled in the top of the member 11 is a drive shaft 16, provided with a beveled gear 17 which meshes with the beveled gear 15, and when the latter is driven, the shaft 6 will revolve an operated fan element to be presently described, so as to overcome the accumulation of sediment at the entrance end of the boiler preventing the retarding and facilitating the passage of the heat units.

A fan element consisting of a casing 18,

is detachably connected to the lower end of thetube 5. The casing 18 has an interiorly threaded nipple 19 which engages with the periphery threads on the lower end of said tube 5. The shaft 6 extends down through the tube 5 and into the casing 18 and carries on its lower end a beveled gear 22, which meshes with a beveled gear 23 carried by a shaft 24 which extends longitudinally from the casin 18 and projects from the rear end thereo The projecting end of the shaft 2e has a fan 25 provided with fan blades 26.

What I claim is An attachment for steam boilers compris- 7 ing a suspended shaft positioned in the boiler near the entrance end thereof, means arranged exteriorly of the boiler for driving the shaft, a suspended tube fixed to the boiler at the entrance end thereof and sur rounding the shaft, said shaft depending from the lower end of said tube, a casing suspended from the lower end of the tube and having said shaft extending therein, a longitudinally disposed shaft extending at right angles with respect to said tube, j ournaled at one end in the forward end of said casing and having its other end projecting in the rear end of said casing, a fan mounted upon the projecting end of the longitudinal shaft, and a gear connection between said shafts and protected by said casing.

In testimony whereof I aflix my signature in the presence of two witnesses.
